[TYPO3-v4] Compressor issues

[Steffen Kamper]

Hi,

looking at the computed output i see some flaws that should be fixed:

* js files are not compressed. There is a call
$filesAfterCompression[$this->compressCssFile($filename)] = $fileOptions;
but it has no effect - result is same file as before, no stripped white 
space, empty lines and comments are not stripped

* js files are not concatenated. This leads to the same amount of 
requests as before.

Imho this should be improved / fixed for RC1
